How do you attach/email more than one document from the pages app?

This is entirely frustrating and I have yet to find an answer for this question even though people have been asking it on the internet for over a year!

I am relatively new to apple and I was considering staying with them for my next iphone because of my apps, but after paying for this app and discovering I can't email more than one document "page" at a time? This makes no sense. Please fix this apple, I'd like to say you have replaced my tablet PC for home-office work but now I am reconsidering...
